The purpose of this experiment was determine the basic properties of a water-based bentonite drilling fluid by obtaining data through implementation of certain devices and the subsequent observation and recording of this data for analysis. The areas of focus of this study involve parameters yielding data such as fluid density or mud weight, fluid viscosity, and gel strength. This data was obtained using a mud balance (figure 1), stopwatch (figure 2), marsh funnel (figure 3), viscometer (figure 4). II. Introduction One of the key components present in the successful drilling of wildcat, developmental, and work over wells is obtaining accurate drilling fluid measurements such as those which record mud weight, viscosity, and gel strength. A drilling fluid, usually referred as mud, “must be able to carry the mud weight to control the well, and circulating.”(1) There are some characteristics that a drilling has to have in order to be able to perform its functions, and two of the very important functions are the mud density or mud weight and viscosity. The mud density is the mass of the drilling fluid and all of its components that are contained in a specific volume of mud. Density is usually measured in pounds per gallon (ppg). “Viscosity is the measurement of the thickness of a fluid. It is measured with a MARSH VISCOSITY FUNNEL and is reported in seconds per quart (liter).”(2) These two characteristic can change during the drilling process and in transit through the drill pipe-bore hole annulus, therefore it is important to monitor the mud weight and viscosity and maintain certain properties and their corresponding values in keeping with the type of strata being penetrated. As a petroleum engineer it is necessary to learn how to use different methods to determine the density and viscosity of the drilling fluid base water, which is the objective of this experiment. Accuracy of such measurements provides the data for understanding the conditions and
